BRACELET.

SPECIFICATION forming part of Letters Patent No. 260,540, dated July 4,1882.

Application filedvMay 16, 1882. (No model.) I

I clear, and exact description of the same, reference being had to theaccompanying drawings, forming part of this specification, in whichFigure 1 is a perspective view of the completedbracelet. Figs. 2, 3, andet are respectively enlarged detail views, showing different steps inthe manufacture of the bracelet;

Fig. 5 is a longitudinal section of one of the coils of the bracelet ascompleted, and provided with the internal spring.

My invention relates to an improvement in flexible bracelets, and in themode of making them. The bracelet consists of. a body portion composedof spiral convolutions of strips of sheet metal bent into half-roundshape in cross-section, and preferably combined with an internal spring,as will be hereinafter more full ydescribed.

I will first describe the construction of the bracelet, and then itsmode of manufacture.

In the drawings, a, Fig. 5, represents a circular or. oval shapedspring, which'may be made with one or more convolutions, of a sizesufficient to inclose the wrist, as in Fig.1. This spring has an outerflexible casing, which constitutes the ornamental exterior'or bodyportion of the bracelet, which casing is composed of spiral strips 1) ofsheet metal, which are of ahollow half-round cross-section, wound inspiral convolutions about the spring, with their convex sides out. Theends of the bracelet as thus described are suitably provided withornamental knobs or heads. The relative size of the spring to the curveof the spiral convolutions of the strips is such as to cause the edgesof the spring to touch said couvolutions and prevent them from beingcrowded past each other, which would strain them into irregularposition. Thebracelet thus formed is perfectly flexible, so that it canbe expanded over the handonto the wrist, and makes a neat, tasty, andsubstantial article of jewelry.

In making the bracelet I take flat strips of plated stock, as shownin'Fig. 2, where the white line indicates the gold and the black thebaser metal, and then draw this strip into a half-tubular shape, asshown in Fig. 3. Then I take preferably two strips of this shape andwind them in spiral convolution upon a brass wire, 0, as shown in Fig.4, and then this brass wire, with its spiral strips of the plated stock,

is wound upon a mandrel smaller than the wrist, so that the expansionwill make it adjustable to any size wrist. Then the wire 0 of base metaland the spirally-wound plated strips being wound a sufticient number ofconvolutions for the bracelet, (which is usually two or three,) it isnext dipped into an acid bath, and the wire 0 and the baser metal ofthespiral strips 1) are dissolved away, leaving the gold plate in thestrips bent into proper form, without being crimped or wrinkled, andforming a light, showy, and elastic body for the bracelet, whoseconvolutions are stifi'ened by their curved form, and kept in place bythe spring, which is afterward inserted and held in place'by theornamental knobs or heads.

I do not confine my invention exclusively to its application in abracelet, as the prinoiple of constructing the bodyportion ot' the sameis also applicable to scarf-rings, necklaces, and analogous articles.

Having'thus described my invention, what I claim as new is- 1. Abraceletor its equivalent having its body portion composed of spirally-woundconvolutions of thin semi-tubular strips of sheet metal, with the convexside outward, as and for the purpose described.

2. A bracelet or its equivalent composed of a circular or oval springwound into one or more convolutions, combined with an externalcasing-composed of strips of half-round or concave sheet metal, Wound inspiral convolutions about the said spring, with their convex sidesoutward,substantially as shown and described.

3. The method of making spirally-wound flexible bracelets or theirequivalents, which consists-in taking plated strips and forming theminto semi-tubular or half-round shape, then winding these spirally upona wire of base metal, then winding thiswire audits spiral strips intolarger convolutions for the wrist, and then dissolving the baser metalsaway and finishing the bracelet, substantially as described.
